eXposure is much faster when using Snow Leopard - the multiple cores of the processor(s) are better utilised under SL so this really speeds up things like eXporting and rendering of high res zooms. The time to do these things is literally halved compared to Leopard.
I think if you're still on 6.01 you may not even have noise reduction and things like the detail window, correct? I would advise upgrading, 7.05 is very stable and fast. I also think there was a problem with colour management in SL until the recent update, because very dark areas would clip to black in the eXposure previews, that weren't clipped in the exported tiff. This problem no longer exists, but I don't know if it was Sinar or Apple who fixed it.
